    Is aloe vera toxic to dogs?

    Aloe leaves contain anthraquinones in their yellow latex that act as a strong laxative. The clear gel is far less of a concern, but chewing the leaf can upset a dog's stomach. The toxic principle is anthraquinone glycosides (e.g. aloin) in the latex layer under the skin.

    Toxic dose by dog weight

The clear inner gel is minimally toxic; the yellow latex causes GI upset. Smaller dogs (toy and small breeds) are generally at higher risk from any given amount.

    How vets treat aloe vera exposure

    Prognosis

    Most dogs treated early do well. The outlook depends on the dose, how quickly care begins, and your dog's overall health. Severe or delayed cases carry a more guarded prognosis.
